Hi All
I m working on setting up PXE boot for SCCM device builds over the network . We are using an SDA network where I have configured IP helper on the SVI the endpoints are connected to . This is the configuration on the Fabric Edge node
SDA-EDGE-POC-1#sh run interface vlan 1025
Building configuration...
Current configuration : 397 bytes
!
interface Vlan1025
description Configured from Cisco DNA-Center
mac-address 0000.xxx.f65d
vrf forwarding Corporate_VN_POC
ip address 10.223.7.1 255.255.255.0
ip helper-address 172.28.251.10 <------------ DHCP Server ( Cisco 3650 switch )
ip helper-address 172.28.86.174 <------------ SCCM Server
ip helper-address 172.28.86.175 <------------ SCCM Server
no ip redirects
ip route-cache same-interface
no lisp mobility liveness test
lisp mobility 10_223_7_0-Corporate_VN_POC-IPV4
end
I m unable to get it working - stuck on the "start pxe over ipv4" screen . As per the attached pcap it look like it doesn't even go past the DHCP Discovery process . However I can also successfully obtain an IP address from the expected DHCP pool while connecting a random device to the same interface . I can then assume routing is not an issue here .
I have not used any DHCP Options as the the IP helper method appears to be the recommendation when the DHCP/SCCM server sit on a different subnet .
Can you please assist ?
Thanks in advance
